Work Experience

Senior Software Engineer

2024 - 2025

ID.me

Proposed the idea, convinced the team, and led the migration to TypeScript, which significantly reduced bugs and improved user rating from 3.4 to 4.2.
Led the migration to React and modular design, which unlocked easy implementation of our total design overhaul down the road.
Suggested the use of Playwright for E2E testing with a PoC, after I noticed a high number of bugs in the project.
Pushed for the use of GitHub Actions to audit and lint, and build all PRs before they can be merged. This led to the discovery of multiple critical vulnerabilities.
Created a workflow that creates a build for each PR automatically and posts it to the PR, eradicating the chore.
Suggested refactoring the whole project to use React routers for UI and Zustand for state, centralizing the state management and removing conditional rendering.
Implemented style and linting rules using Prettier, custom ESLint files, and Husky, and finally enforced them using GitHub Actions. This created a unified codebase coding style.

Users can use Klarna's Chrome extension to pay anywhere, including top brands like Macy's, eBay, Walmart, and Nike. It provides users with automatic coupons, cashback, and one-time cards in four interest-free installments. I've worked on developing and debugging several parts of the extension.
